Detailed Analysis of Each Match.
Lectin, such as Concanavalin-A, is specifically known for binding carbohydrates and not amino acids; hence, A-III is the correct match.
Neutral amino acids, like Valine, are characterized by their non-polar side chains and are essential in biosynthetic processes, making B-IV the correct choice.
Aromatic amino acids, typically involved in forming complex protein structures, match with Tyrosine, which is itself an aromatic amino acid, making C-I a correct identification.
Collagen, a fibrous protein in connective tissues, matches with Protein, making D-II appropriate.
